I have the customary mappings for :help,
nmap <F1> :exec "help " . expand("<cword>")<CR>
nmap <S-F1> :exec "help " . expand("<cWORD>")<CR>
and have been trying to develop similar do the <Tab> option on the cursor
word, something like
nmap \\ yiw:h ^R"^[
But ^[ means Escape, not Tab,
and Escape, when used in a mapping, works like Enter (usually):
:h c_Esc
So you want <Tab> (right?) which looks more like ^I, but anyway in a mapping you
can't use <Tab>,
instead you need to use the key defined with
:h 'wildcharm
(:set wcm=<C-_> works for me).
but to no avail. Although the mapping does not terminate with a <CR>, vim
treats the ^[ as if it were <CR> rather than <Tab> and goes straight to the
specific help for the cursor-word.
Is it possible to have vim act on the <Tab> as it does in the command line?
Your mapping becomes (with above 'wcm' setting):
:nnoremap \\ yiw:h <C-R>"<C-_>
or
:nnoremap \\ :<C-U>h <C-R><C-W><C-_>
or (I think I'd use)
:nnoremap <Leader><Tab> :<C-U>h <C-R><C-W><C-_>
